ORA-02327: cannot create indexes on the LOB data type expression

DB 10.2.0.4
DB 5.2

I am not able to move lobindex and lobsegment. While try occurs below error

SQL > ALTER INDEX dev. "" SYS_IL0000718396C00002$ $"REBUILD THE TABLESPACE DATA_TEMP;
ALTER INDEX dev. "" SYS_IL0000718396C00002$ $"REBUILD TABLESPACE DATA_TEMP

ERROR on line 1:

Thank you

correct syntax is
ALTER TABLE.

MOVE the LOB ()
STORE AS (tablespace );

Where is a name of the / columns LOB, not the name of the segment. Moving type LOB data will move its indexes as well.

Hello

You code works very well for me. I had to change to run on my system tablespaces, but otherwise, what you posted worked for me when I tried (in a different schema than SYS, of course).

How to use the LOB data type?

I can't create a table with the LOB data type.
Do I need an additional parameter in sys.odbc.ini?
My dsn information is
[tpch]
Driver=/home/TimesTen/TimesTen/tt1121/lib/libtten.so
Data store = / home/timesten/TimesTen/tt1121/tpch/tpch
LogDir = / home/timesten/TimesTen/tt1121/tpch/logs
PermSize = 4096
TempSize = 2048
PLSQL = 1
LOB = 1
DatabaseCharacterSet = US7ASCII
-bash-4, $ 1 ttdaemonadmin-version
TimesTen Release 11.2.1.2.0

There is no LOB = 1 attribute; Please, delete it from your definition ODBC to avoid potential errors.

LOB support has been added in the major version 11.2.2 TimesTen. So you use 11.2.1 LOB is not available. If you want to use LOB data, then you must upgrade to 11.2.2.

Stream uses system global area (SGA) memory to store the information required to capture and apply. To allocate memory from the SGA for use by water courses, establish a flow pool in the SGA by specifying the STREAMS_POOL_SIZE parameter. The default value for this setting is 0, which means that the stream instead uses the shared pool memory. If you leave the STREAMS_POOL_SIZE to its default value (0), water courses will be considering using up to 10 percent of the SHARED_POOL_SIZE, then Oracle recommends at least 200 MB for the STREAMS_POOL_SIZE parameter. The source and destination databases must take account of this memory in the SGA.

Syntex to create the table with the long data type

I'm looking to create a table based on another table that having the column long data type. Throw the error ORA-00997: illegal use of the LONG data type

I tired it
create table abc_long (ag bgd long number);
create table abc_long_dummy as ( ) Select *of abc_long); - ORA-00997 error: illegal use of the LONG data type
How to get there?

I'm looking to create a table based on another table that having the column long data type.

You really don't want to do that.

LONG data type has been deprecated for some time now, use CLOB.

The TO_LOB() function will do the conversion on the fly:
```
create table abc_long_dummy
as
select ag
     , to_lob(bgd) as bgd
from abc_long ;
```

ORA-19504: cannot create the file '+ DATA '.

Hello everyone.
This is the scenario:
We have a test server that is used to restore daily backups of the Production database. Restore us the database with the same SID as the production one.
For specific reasons, we need create a second database (with a different SID) on this server with an older backup from the production one. To realize that I'm trying to use a part of the "DUPLICATE without connection to the target" tutorials on the web.
I tried the simple guide that I found which is:
(1) copy the backup files cold /somedirectory
(2) start OLD database with nomount
(3) connect RMAN with OLDER as an auxiliary
(4) run the following: DUPLICATE DATABASE FOR OLD BACKUP LOCATION ' / somedirectory' NOFILENAMECHECK.
Here's the result (I deleted some lines because of the size of it):
----------------------

The first mistake of the stack was ORA-19504 while trying to restore the backup of the database.
First thing I took a glance was ASM occupation but it enough available space.
The second was a permission problem, but it doesn't seem to be the case because RMAN can correctly write the controlfile to ASM.
One have some advice on what I should look for?
Thanks in advance sorry for my English.
Select this option.

Hello.

Thanks, but is not the case. As I have said, that the DATA diskgroup has space enough he uses only a single disk in a RAID.

But I solved my problem... To the auxiliary database, I added the following to the spfile:

DB_FILE_NAME_CONVERT = '+ DATA/ProdDB', '+ DATA/OlderDB ".

LOG_FILE_NAME_CONVERT = '+ DATA/ProdDB', '+ DATA/OlderDB ".

I don't know why, but with these two clauses, it worked well. Perhaps RMAN was trying to restore it to the wrong place?

ORA-12913 cannot create the dictionary managed during import tablespace
Greetings,
I'm a newbie om moving databases between servers.

I get the following error: "ora-12913 cannot create tablespace dictionary managed" when executing the data pump import. It is a 10.2.0.4 database that I'm moving from HP - UX PA-RISC to HP-UX-Itanium. It seems that all managed tablespaces locally were ok. Some of the successful dictionary tablespaces had problems (DRSYS, INDX, RBS, TOOLS)

Should I convert all tablespaces dictionary managed locally managed tablespaces before data pump export/import? Note that this is a very small database with little use, then what better practical performance I'd like to hear.

Thanks colin

Published by: YJC on Aug 17, 2010 15:16
>
(1) should all be converted to Locall managed?
(2) can the RBS safely deleted, given that an UNDO tablespace that uses the DB.
>

Only the SYSTEM will have to be migrated to managed locally. The RBS tablespace can be deleted if there is a separate UNDO tablespace and the database uses undo automatic management.

Why I can't create indexes on the table of RDF data

When I tried to create indexes on the table of RDF data, it always say the table or view does not exist. I created the RDF model using java codes:
Oracle Oracle = new Oracle ("jdbc:oracle:thin:@localhost:1521:orcl", "system", "123");
Chart GraphOracleSem = new GraphOracleSem (oracle, "test2");

And used the following commands in sqlplus to create indexes:
SQL >
SELECT THE SEPARATE OWNER, OBJECT_NAME
FROM DBA_OBJECTS
WHERE TYPE_OBJET = 'TABLE '.
4. AND OBJECT_NAME like ' % TEST2;
OWNER
--------------------------------------------------------------------------------

Hi Shifu,

It is not recommended to use the SYS or SYSTEM to store/manage schema graph RDF data.

Can you please try the following in a SQL * more terminal?

SQL > conn system/eu1

Connected.

"Getting Started" VM said "ORA-01471: cannot create a synonym.

People,
I downloaded the VM with demo integration OGG + ODI for 12.1.3, as well as the PDF "Getting Started with Oracle Data Integrator 12 c". Try step 10.3.2 on pg 92: "Initial running load staged Mapping", but it throws the error message:
ODI-1228: task Create synonym on target-LKM Oracle for Oracle (DBLINK) - fails when connecting the TRG_ODIDEMO target.
Caused by: java.sql.SQLException: ORA-01471: cannot create a synonym with the same name as the object
He told the truth, I tried the code in sqlplus with the same error:
SQL > conn odi_staging/oracle;
Connected.
SQL > create synonym ODI_STAGING. C$ _0OGG_CUSTOMER1 for ODI_STAGING. C$_0OGG_CUSTOMER1@ORCL;
ERROR on line 1:
ORA-01471: cannot create a synonym with the same name as the object
Initially, the definition of database server did not have the Instance = orcl inside, I added and got the same error with and without "orcl". Why is this happening? Another odd piece that may be associated with: I tried this mapping even earlier, and it got stuck on the front line, trying to create a view, but was insufficient privs for ODI_STAGING select the ogg_customer table. So I just did "grant dba to odi_staging;" and that was not enough! Tried stop/start ODI, then the DB without change. Hmmm, s/n role not enough? I've also had "grant select any table of odi_staging;", then this line worked.
Back to the current problem: I can get the other procs to run, as the Clean Up target tables works very well, and the demo Client works very well.
(1) anyone has experience this problem of synonym?
(2) no matter who else get it to work?
-Thanks, Steve F.

I got the fix in the product manager. There are two very similar LKMs:
- LKM Oracle for Oracle (DBLINK) (must be imported)
- LKM Oracle for Oracle shoot (DB Link). GLOBAL (integrated)
Of course, they look the same to me except that the second works and one doesn't. In all honesty, the book on pg 89 says 'Pull' in the name. Chalk it up to user error. Detective Conan.

How to create indexes on the ordered collection of XMLTYPE table?

I use Oracle 11.2.0.2.

Basically, my XML documents have a 3-level hierarchy:

event

+ - action [1: n]

+ - param [1: n]

I try to create indexes on the tables of the orderly collection, but cannot get the right syntax...

I created a table with an XMLType object-relational column:

CREATE TABLE T_C_RMP_MNTRNG_XML_FULL_IL4 (
  MESSAGE_ID NUMBER(22,0) NOT NULL ENABLE,
  XML_EVAL_ID NUMBER(22,0),
  VIN7 VARCHAR2(7 BYTE),
  FLEET_ID VARCHAR2(50 BYTE),
  CSC_SW_VERSION VARCHAR2(100 BYTE),
  RECEIVED DATE,
  XML_CONTENT SYS.XMLTYPE ,
  DWH_LM_TS_UTC DATE NOT NULL ENABLE,
  CONSTRAINT PK_C_RMP_MNTRNG_XML_FULL_IL4 PRIMARY KEY (MESSAGE_ID)
) NOLOGGING TABLESPACE CATALOG
VARRAY "XML_CONTENT"."XMLDATA"."action" STORE AS TABLE "T_OR_MON_ACTION" (
  NOLOGGING TABLESPACE "CATALOG"
  VARRAY "param" STORE AS TABLE "T_OR_MON_ACTION_PARAM" (
  NOLOGGING TABLESPACE "CATALOG"
  ) RETURN AS LOCATOR
) RETURN AS LOCATOR
XMLTYPE XML_CONTENT STORE AS OBJECT RELATIONAL XMLSCHEMA "http://mydomain.com/cs.xsd" ELEMENT "monitoring";

I execute the SELECT statement:

SELECT EVENT_ID, ACTION_SUB_ID, MESSAGE_ID, ACTION_TYPE, UNIXTS_TO_DATE(ACTION_TIMESTAMP) ACTION_TIMESTAMP
FROM T_C_RMP_MNTRNG_XML_FULL_IL4, 
XMLTABLE( 
  'for $i1 in /monitoring , 
  $i2 in $i1/action            
  return element r {              
  $i1/eventId,              
  $i2            
  }' 
  PASSING XML_CONTENT COLUMNS 
  EVENT_ID VARCHAR(40) PATH 'eventId', 
  ACTION_SUB_ID INTEGER PATH 'action/actionSubId', 
  ACTION_TYPE VARCHAR2(100) PATH 'action/type', 
  ACTION_TIMESTAMP NUMBER(13,0) PATH 'action/time' 
) T2 
WHERE ( 
  EVENT_ID IS NOT NULL AND ACTION_SUB_ID IS NOT NULL 
)

How can I create an index on these tables of the ordered collection to improve performance?

I found the example at http://docs.Oracle.com/CD/E11882_01/AppDev.112/e23094/xdb_rewrite.htm#ADXDB5859 but am not able to apply to this particular case...

Thank you in advance...

If the schema is not annotated and XS: Integer and XS: String are mapped to types of data NUMBER and VARCHAR2 (4000), so you must use in your query to avoid typecasting unnecessary operations.

You must also use XMLTABLEs chained when accessing a parent/child instead of a FLWOR expression relationship, otherwise the CBO cannot rewrite the XQuery query correctly (maybe it's fixed in the latest version).

If you make these changes, the plan should show the cleaner predicates:

SQL > SELECT EVENT_ID, MESSAGE_ID, ACTION_TYPE, ACTION_SUB_ID, ACTION_TIMESTAMP

2 FROM test_table

3 XMLTABLE ('/ monitoring ')

4 COLUMNS XML_CONTENT OF PASSAGE

5 WAY of VARCHAR2 (4000) EVENT_ID "ID."

6 actions for XMLTYPE PATH 'action '.

(7) T1,

8 XMLTABLE ('/ action')

Shares of PASSAGE 9 COLUMNS

NUMBER of ACTION_SUB_ID 10 PATH "actionSubId."

11 PATH of VARCHAR2 (4000) ACTION_TYPE "type."

12 WAY of NUMBER ACTION_TIMESTAMP 'time '.

(13) T2

14 WHERE EVENT_ID IS NOT NULL

15 AND ACTION_SUB_ID IS NOT NULL

16;

Now, if it is still necessary, everything boils down to choosing a technique for index NULL values:

-composite index with a column not zero or constant

-FBI

-bitmap image

Choose the one that best fits your data, the selectivity and activity on the tables.

ORA-19504: cannot create file when using rman
Hello
on 10g bR2 on windows machine my rman backup failed on a drive mapped with following error message:
ORA-19504: cannot create file when using rman

What do you suggest me?

I heard that RMAN cannot write to the mapped file system. Is this true? Some people proposed:

OracleService must be run by OS user with permissions

But what oracle service? Target or RMAN catalog database database?

Thank you.

Creating indexes for the table

can someone help me how to create indexes in the table. I m creating own table... I need to select a particular field in the table. So I need to calculate the index position. I use my code like this,

This will returnthe number of columns in the table.

Class array

{

private int Table_Index()
{
for (int x = 0; x)<>
{
table_index = x;
}
Return table_index;
}

}

MainClass can I get this length of Index

Table T1;

int t1 is T1. Table_Index();

This property returns my length (4) of table column

Using this index (t1) I HAV to see what position I'm at table now...

someone help me...

You can use a listfield, he supports methods to get the selected row and its contents.

How to create indexes on the nested table.
Hi all
I held the syntax to create indexes on the nested table.

I found below synta but when I try it with my table it gives me error

CREATE UNIQUE INDEX indx_name
ON nestedtablestore (NESTED_TABLE_ID, id);

What is here NESTED_TABLE_ID & ID
They are virtual your nested table

Here is an example.
```
create or replace type obj as object (no integer, address varchar2(100))
/
create or replace type tbl as table of obj
/
create table test_tbl (id integer, name varchar2(100), address tbl) nested table address store as address_nt
/
create unique index address_no_idx on address_nt (no, address)
/
```
